Reference in the specification to “one embodiment” or “an embodiment” ofthe present principles, as well as other variations thereof, means thata particular feature, structure, characteristic, and so forth describedin connection with the embodiment is included in at least one embodimentof the present principles. Thus, the appearances of the phrase “in oneembodiment” or “in an embodiment”, as well any other variations,appearing in various places throughout the specification are notnecessarily all referring to the same embodiment.

It is to be appreciated that the use of any of the following “/”,“and/or”, and “at least one of”, for example, in the cases of “A/B”, “Aand/or B” and at least one of A and B” is intended to encompass theselection of the first listed option (A) only, or the selection of thesecond listed option (B) only, or the selection of both options (A andB). As a further example, in the cases of “A, B, and/or C” and “at leastone of A, B, and C”, such phrasing is intended to encompass theselection of the first listed option (A) only, or the selection of thesecond listed option (B) only, or the selection of the third listedoption (C) only, or the selection of the first and the second listedoptions (A and B) only, or the selection of the first and third listedoptions (A and C) only, or the selection of the second and third listedoptions (B and C) only, or he selection of all three options (A and Band C). This may he extended, as readily apparent by one of ordinaryskill in this and related arts, for as many items listed.

Referring to the drawings in which like numerals represent the same orsimilar elements and initially to FIG. 1, an exemplary system 100 foraerial transportation of delivery items using an unmanned aerial vehicle102 is illustratively depicted. It should he understood by one ofordinary skill in the art that the unmanned aerial vehicle 102 maycomprise a drone, a drone-like: unit, or a similarly functioning device.

Advancements in unmanned aerial vehicles (UAVs) and/or drones have beenimplemented for delivery services of such consumer goods. For example, adelivery drone, also known as a parcelcopter, may transport packages,food, medicines, and other goods with delivery times much faster thantraditional transportation methods (e.g., minutes). In addition, dronesused for delivery services also enable delivery of such goods to remotelocations that are difficult to get to by traditional transportationmethods due to varying terrain on such delivery routes.

The unmanned aerial vehicle 102 may include a housing unit 104, at leastone movement mechanism 106, and a motor 108. The components of theunmanned aerial vehicle 102 may he affixed on the outside of the housingunit 104, or alternatively, may be enclosed within the housing unit 104of the unmanned aerial vehicle 102.

The at least one movement mechanism 106 may include a single propeller,a plurality of propellers, a propulsion mechanism, or similarlyfunctioning devices to provide aerial movement for the unmanned aerialvehicle 102. In one embodiment, the at least one movement mechanism mayhe powered by at least one motor 108, such as a gasoline engine,electric motor and/or a power supply 110 to provide movement for theunmanned aerial vehicle 102. The power supply 110 may include a battery,such as a rechargeable battery, and/or solar powered battery sufficientfor powering the unmanned aerial vehicle 102 and/or components of theunmanned aerial vehicle 102.

The movement mechanism(s) 106 may he placed at any desired location onthe unmanned aerial vehicle 102, such that the placement of the movementmechanism(s) 106 does not interfere with each other or with anothercomponent positioned on the unmanned aerial vehicle 102 and/or housingunit 104. In one embodiment, the at least one movement mechanism 106 mayhe positioned on at least one extension arm 107 such that the at leastone extension arm 107 connects the at least one movement mechanism 106to the housing unit 104.

In some embodiments, the at least one movement mechanism 106 and/orextension arm(s) 107 may he spaced around the unmanned aerial vehicle102 and/or positioned such that the unmanned aerial vehicle 102maintains a balanced orientation. A balanced orientation may be a stateof equilibrium in which the unmanned aerial vehicle 102 may enable anefficient flight. In further embodiments, the position of the at leastone movement mechanism 106 and/or extension arm(s) 107 may be adjustedsuch that the unmanned aerial vehicle 102 maintains a balancedorientation. For example, the movement mechanism(s) 106 and/or extensionarm(s) 107 may pivot and/or hinge from the housing unit 104 of theunmanned aerial vehicle 102 in various directions. In some embodiments,the position of the extension arms 107 may he adjusted and/orrepositioned when the unmanned aerial vehicle 102 carries a deliveryitem (not shown) via attachment device 126 to maintain a balancedorientation.

In one embodiment, the movement mechanism 106 and/or motor 108 providesaerial movement for the unmanned aerial vehicle 102 in multiple degreesof freedom. Multiple degrees of freedom generally refers to the abilityfor the unmanned aerial vehicle 102 to move in a three-dimensionalspace. Specifically, the movement mechanism 106 and/or motor 108 may becontrolled by controller 101, such as a flight controller 502, asillustrated in FIG. 5, to move the unmanned aerial vehicle 102 alongthree perpendicular axes, namely forward/backward movement, up/downmovement, and left/right movement. In addition, the controller 101 maycontrol the movement of the unmanned aerial vehicle in 360 degreerotation, tilting forward/backward movement (e.g., pitching), swivelingleft/right movement (e.g., yawing), and pivoting side to side movement(e.g., rolling).

In one embodiment, the movement mechanism(s) 106 and/or motor 108provides movement for the unmanned aerial vehicle 102 to deliver one ormore items to a particular destination. For example, the movementmechanisms 106 and/or motor 108 may enable the unmanned aerial vehicle102 to aerially transport delivery items from a shipping location to aparticular delivery destination, such as a consumer's location and/orshipping address. In further embodiments, the movement mechanism 106and/or motor 108 may provide aerial movement to the unmanned aerialvehicle 102 to base stations, recharging stations, shipment facilities,and/or locations of other unmanned aerial vehicles to, for example,recharge the power supply 110, as will be described in further detailbelow. In vet a further embodiment, the movement mechanism(s) 106 and;or motor 108 provides movement for the unmanned aerial vehicle 102 toavoid collision between the unmanned aerial vehicle 102 and an object,such as a person, tree, building, and/or other structures.

In some embodiments, the attachment device 126 fastens a delivery item(not shown) to the unmanned aerial vehicle 102. The attachment device126 may include, but is not limited to, a latch, a hook or claw, asuction device, a magnetic device, or combination thereof, and/or anyother device capable of temporarily attaching (e.g., fastening) thedelivery item to the unmanned aerial vehicle 102 and releasing (e.g.,unfastening) the delivery item upon delivery. In an embodiment, theattachment device 126 ma include a retractable wire which may bepermanently attached to the housing unit 104 at one end and, at theother end, may include a hook, latch, or further accessory to connectthe delivery item to the wire and/or unmanned aerial vehicle 102.

In some embodiments, the attachment device 126 may include a compartmentand/or enclosure to store the delivery item on the unmanned aerialvehicle 102 until delivery. The compartment may be integrated with theunmanned aerial vehicle 102 and/or may be attached to the unmannedaerial vehicle 102. In further embodiments, the compartment and/orenclosure may be temperature controlled by one or more sensors 114and/or a temperature controller 116 to, for example, provide protectionto perishable items, such as foods, medicines, life-forms (e.g., plants,animals), etc. In a further embodiment, the attachment device 126 (e.g.,compartment) may be thermally insulated. For example, the attachmentdevice 126 may comprise and/or include insulating material within thecompartment.

In a further embodiment, the attachment device 126 may include adampening and/or absorbent material, thermal or acoustical insulation,and/or inflatable air compartments configured to reduce and/or mitigatesound (e.g., noise) and/or vibration generated from, for example, themovement mechanism(s) 106 and/or motor 108 during flight. The dampeningmaterial and/or air compartments may further protect fragile items beingdelivered by the unmanned aerial vehicle 102. The dampening material maybe disposed at any location within and/or on the attachment device 126.For example, when the attachment device 126 is a compartment, thedampening material may be placed as a liner within the compartment.

The unmanned aerial vehicle 102 may he configured to engage and/ordeploy the attachment device 126. For example, the unmanned aerialvehicle 102 may close a latching device so as to “lock” a delivery itemto the unmanned aerial vehicle 102. In addition, the unmanned aerialvehicle 102 may open the latching device so as to release the deliveryitem upon delivery. In some embodiments, the unmanned aerial vehicle 102may he configured to deploy the retractable wire to a sufficient heightabove the ground to enable safe delivery of the delivery item.

The unmanned aerial vehicle 102 may further include a controller 101configured to control one or more components of the unmanned aerialvehicle 102. For example, the controller 101 may control at least onecamera 112, at least one sensor 114, a temperature controller 116, astability controller 118, an alert system 120, a speaker 122, and/or atransceiver device 124.

The camera 112 may he configured to provide visual feedback, such as oneor more still images and/or video feedback, to the unmanned aerialvehicle 102 and/or an operator (e.g., user) wirelessly controlling theunmanned aerial vehicle 102. For example, the camera 112 may providevisual feedback of obstacles in the path of the unmanned aerial vehicle102 for any purpose, such as, but not limited to, navigation guidance tothe unmanned aerial vehicle 102. In a further embodiment, the camera 112may determine a safe location for the unmanned aerial vehicle 102 toland and/or disengage the attachment device 126 to deliver the item. Thecamera 112 may capture one or more still images or video images and,using a database, may perform image comparison with database images,such as database 510 of FIG. 5, to determine whether or not the locationis safe to land and/or release the delivery item. For example, thecamera 112 may capture an image of a rooftop of a building and, usingimage comparison, the camera 112 may identify the rooftop as an unsafelocation to release the delivery. It should be understood that varioustypes of cameras are contemplated, including high-definition cameras,night-vision enabled cameras, infrared sensing cameras, X-ray imagingdevices, line scan imaging devices, etc.

In a further embodiment, the camera 112 may he configured to take one ormore still images and/or video upon delivery of an item. For example,when the unmanned aerial vehicle 102 delivers an item at a destinationlocation, the camera 112 may capture a photo and/or video of thereleased delivery item at the delivery location and/or the locationitself to confirm delivery and/or location of such item. The unmannedaerial vehicle 102 may provide delivery notification and/or deliverylocation information to the recipient by transmitting the photo and/orvideo to a user device 132 (e.g., a mobile device, tablet, computingdevice, etc.) via transceiver 124 and/or transmission medium 128.Accordingly, the recipient can confirm the time and/or actual locationwhere the delivery item was physically delivered.

The camera 112 may be placed on the unmanned aerial vehicle 102 suchthat the camera may provide visual feedback in 360 degrees on ahorizontal plane and/or 360 degrees on a vertical plane of the unmannedaerial vehicle 102. In some embodiments, the camera 112 may include aplurality of cameras to provide visual feedback in all directionssurrounding the unmanned aerial vehicle 102 such that there are noobscurations of the visual field (e.g., blind spots). In furtherembodiments, the camera 112 may he embedded within the housing unit 104so as to prevent any negative effects to aerodynamics of the unmannedaerial vehicle 102.

In an embodiment, the unmanned aerial vehicle 102 may include at leastone sensor 114. The sensor 114 may include, but is not limited to, anacoustic sensor (e.g., microphone), a chemical sensor, an infraredsensor, an optical sensor, a collision avoidance sensor (e.g., aproximity sensor), a heat/temperature sensor, a gravitation force sensor(e.g., accelerometer), a speed sensor (e.g., airspeed indicator), tiltsensor, etc.

In an embodiment, the sensor 114 may be configured to detect one or moreenvironmental variables, such as temperature, acceleration, (e.g.,changes in acceleration), tilt angle, cumulative turbulence, windresistance, exposure to sunlight, oxygen levels, pressure (e.g.,atmospheric pressure), humidity, etc., associated with the unmannedaerial vehicle 102 and/or traversed during flight, which may bedisplayed on and/or generated by the alert system 120 to one or moreindividuals (e.g., an observer, recipient, etc.), as will be describedin further detail. It should be understood that the term “environmentalvariables” should not be limited and may include other variablesdetected by sensor 114 and/or experienced by an unmanned aerial vehicle102 during flight.

In an embodiment, detecting temperatures experienced and/or traversedduring flight may determine, for example, assessment of risk to aperishable object during flight and/or upon deliver of such object. In afurther embodiment, the sensor 114 may detect one or more environmentalvariables (e.g., temperature) during flight such that when anenvironmental variable (e.g., a temperature) exceeds a predeterminedthreshold, the alert system 120 may generate an alert, such as a visualand/or audible warning indicating that the delivery item requiresimmediate attention. In a further embodiment, the alert system 120 maytransmit an instruction and/or command to the temperature controller 116to provide heating and/or cooling to the attachment device 126 (e.g.,compartment) and/or deliver item to prevent perishing of the item.Perishable items may include, but are not limited to, food, liquids,medicines, life-forms (e.g., animals, such as mealworms and/or fish,plants), etc.

In some embodiments, the sensor 114 may be configured to detect variousenvironmental variables traversed by the unmanned aerial vehicle 102during flight including, but not limited to, acceleration, and/orpercentage of tilt. The detected level of acceleration, and/or tilt maybe displayed on the alert system 120 to, for example, assess overallflight environment and/or issue a command to the stability controller118 to provide a more stable flight environment where acceleration, tiltand/or orientation are critical, such as during the delivery of animalsor fragile items.

In some embodiments, the sensor 114 may detect measurements of at leastone of acceleration and/or tilt, and the alert system 120 limy transmitsuch measurements to the stability controller 118 to determine, forexample, adjustments to maintain a balanced orientation of the deliveryitem(s) attached to the unmanned aerial vehicle 102 to provide abalanced load. In some embodiments, measurements of acceleration and/ortilt may be stored in a database, such as databased 510 of FIG. 510, tocoordinate flight planning for future flights so as to reduceacceleration and/or tilt during flights over the same terrain.

The stability controller 118 may be configured to determine appropriateload distribution of the delivery item(s) such that the load is balancedand/or evenly displaced based on the measurements detected by the sensor114 prior to flight. In some embodiments, the stability controller 118may be configured to receive dimension and/or weight information of eachdelivery item and arrange the delivery item(s) along the unmanned aerialvehicle 102 to maintain a balanced load for an efficient flight.

In a further embodiment, the sensor 114 may be configured to detectproximity to objects and/or obstacles in the path of the unmanned aerialvehicle 102 for any purpose such as, but not limited to, navigationguidance to the unmanned aerial vehicle 102. In some embodiments, thesensor 114 may he configured to determine a distance between theunmanned aerial vehicle 102 and a detected object to avoid collision.

The unmanned aerial vehicle 102 may include an alert system 120. Thealert system 120 may be a readily detectable status indicator mounted onthe outside of the unmanned aerial vehicle 102 configured to generate analert and/or status associated with the unmanned aerial vehicle 102and/or delivery items along a delivery route. For example, thealert/status may include a progress level and/or level of taskcompletion, such as delivery status of an item to a predetermineddestination, an amount of time spent traveling, the amount of time leftto reach the destination, a dollar value associated with the one or moreitems being transported, percentage of an order fulfillment, and/orenvironmental factors detected by the sensor 112 and experienced by theunmanned aerial vehicle 102 during flight.

The alert system 120 may include a light display, an illuminated colordisplay, a digital timer display, a clock display, an acoustic signal,and/or an electronic signal. For example, the, alert system 120 mayinclude a plurality of lights positioned peripherally around the housingunit 104 of the unmanned aerial vehicle 102 configured to displayvarious colors and/or patterns (e.g., solid, flashing, multi-coloredpattern of lights) to an observer and/or recipient indicatinginformation associated with the unmanned aerial vehicle 102. The lightpattern can include one or more colors which may be static (e.g.,non-moving) and/or dynamic (e.g., moving, such as flashing). It shouldbe understood that the particular light pattern for taking off, landing,and/or level of progress may be set by the industry and/or user.

In an embodiment, the alert system 120 may be configured to generate anacoustic signal, such as a beep, alarm, and/or spoken words, to indicateand/or announce information associated with the unmanned aerial vehicle102 during flight. For example, the alert system 120 may provide variousspoken announcements and/or commands (e.g., “Caution”, “Landing”, “Stayclear”, etc.) via speaker 122 to observers. Alternatively, the alertsystem 120 may be configured to transmit and/or broadcast an electronicsignal and/or command, via transceiver 124, to a receiving device, suchas an observer's cellular telephone (e.g., user device 132). Theelectronic signal may indicate various information associated with theunmanned aerial vehicle 102.

In some embodiments, the alert system 120 may be observed from multipleviewpoints. For example, the alert system 120, such as a light displayon the unmanned aerial vehicle 102, may be observed by a person on theground, an air traffic controller tower, and/or various aircraftvehicles. In other embodiments, the alert system 120 may include aspeaker configured to provide an audible signal indicating informationassociated with the unmanned aerial vehicle 102, which may be otherwiseperceived by one or more individuals.

The present principles provide at least one of the following advantages,lamely, a readily detectable indicator mounted on the unmanned aerialvehicle 102 readily observable to individuals configured to generate astatus associated with the unmanned aerial vehicle 102, such asmovements of the unmanned aerial vehicle 102 and/or an assessment ofrisk to perishable delivery items and/or battery life of the unmannedaerial vehicle 102, especially when fragile items are being delivered.In some embodiments, observers are able to readily determine directionalmovement and/or flight status of the unmanned aerial vehicle 102, suchas whether the unmanned aerial vehicle 102 is taking off, landing,turning, etc. Accordingly, observers can readily determine the flightstatus of the unmanned aerial vehicle 102 and avoid a particular area.

The alert system 120 may illuminate lights of a particular color and/orpattern. For example, the alert system 120 may illuminate lights (e.g.,flashing red lights) indicating the unmanned aerial vehicle 102 is aboutto take-off and/or land. During flight, the alert system 120 maycontinuously illuminate lights along the unmanned aerial vehicle 102 asthe unmanned aerial vehicle 102 approaches the delivery locationindicating a status of the delivery. For example, assuming the alertsystem 120 includes a total of 100 lights arranged along the peripheryof the unmanned aerial vehicle 102, the alert system 120 may illuminatetwenty-five adjacent lights when delivery is twenty-five percentcomplete, fifty adjacent lights when delivery is fifty percent complete,etc. In another embodiment, the alert system 120 may illuminate, one ormore lights indicating how much time is left before landing and/ordelivery. In a further embodiment, the alert system 120 may generate adistinct color and/or pattern when delivery has been completed and/orthe unmanned aerial vehicle 102 is returning to the shipment facilityand/or base station. Accordingly, an observer can readily determine thatan unmanned aerial vehicle 102 flying nearby presents no hazard to theobserver. It should he understood that mapping of such colors and/orpatterns displayed by the alert system 120 may be set by industrystandard.

The alert system 120 may provide additional details about the unmannedaerial vehicle 102 and/or delivery item(s). For example, the alertsystem 120 may generate a dollar value associated with the deliveryitem(s), which may change during the course of delivery. The alertsystem 120 may illuminate one or more visual displays, such as a colorpattern, indicating if the delivery item(s) are of high dollar valuesuch that the recipient can arrange to be present for delivery and/orattend to the delivery item(s) immediately upon delivery. Accordingly,the alert system 120 can generate a status indicating to the recipientthe dollar value of the delivery item(s) such that the recipient canprevent thievery of the delivery items upon delivery. In someembodiments, the visual display (e.g., color pattern) indicating thedollar value of the delivery item(s) can be mapped, set or otherwisecontrolled by the recipient via user device 132 such that only therecipient is aware of the dollar value associated with the visualdisplay of the alert system 120.

In some embodiments, the dollar value of the delivery item(s) may changethroughout the delivery if, for example, the delivery item(s) areperishable, which may be indicated by the alert system 120. The dollarvalue of the delivery item may decrease when one or more environmentalvariables exceeds a predetermined threshold. For example, when adetected temperature is above melting point, a delivery item (e.g., icecream) may melt, and the value of the delivery item may decrease. Thealert system 120 may indicate the change in dollar value of suchdelivery item.

In some embodiments, the alert system 120 may provide the recipient ofthe delivery item with an up-to-date estimated time of delivery. Forexample, the alert system 120, in combination with a navigation unit,such as navigation unit 504 of FIG. 5, may estimate time of deliverybased on approximate distance to the delivery location and/or velocity(e.g., airspeed) of the unmanned aerial vehicle 102. The estimated timeof delivery determined by the alert system 120 may be transmitted and/orotherwise communicated to the recipient, such as a user device 132, viathe transceiver 124 and/or transmission medium 128. In addition, theuser device 132 may prompt/request the alert system 120 to provideupdated information associated with the unmanned aerial vehicle 102including, but not limited to, estimated time and/or date of delivery.

In an embodiment, the alert system 120 may provide the recipient withdelivery notification, such as delivery of the item and/or a percentageof order fulfillment (e.g., 50%, 1 out of 2, etc.) when multipledeliveries are expected. Accordingly, the recipient of the deliveryitem(s) may better estimate when delivery is expected and arrange to bepresent for delivery so as to prevent theft of the delivery item(s) upondelivery. In addition, the alert system 120 may indicate and/or displaywhich part of an order is being delivered When, for example, orders aresplit into several packages and/or several deliveries (e.g., amongmultiple drones).

In some embodiments, the unmanned aerial vehicle 102 may automaticallyreorder delivery items if the alert system 120 indicates loss of suchitem. For example, if a delivery item is lost and/or damaged duringflight (e.g., the attachment device 126 inadvertently releases adelivery item before delivery), the alert system 120 may identify thelost item and request replacement of such item via the transceiver 124.The transceiver 124 may communicate with a secondarytransmitter/receiver device 130, such as a secondary drone 134, toobtain and deliver such item to the delivery location.

In some embodiments, the alert system 120 may indicate a total amount oftime spent traveling from the shipping location and/or a batteryrecharging station to the delivery location. Determining the totalamount of time spent traveling may be used, for example, to assess alevel of risk to perishable items and/or the battery life of the powersupply 110. For example, the alert system 120 may track and/or display atotal amount of time spent traveling with a perishable delivery item.Upon delivery of the item, the alert system 120 may flash red lights,initiate a beeping noise and/or announcement via speaker 122, broadcastan electronic signal via transceiver 124, and/or provide a signalindicating to the recipient and/or an observer that the delivery item isperishable and/or needs immediate attention based on the total amount oftime spent traveling. Accordingly, the alert system 120 may furtherprevent spoiling of perishable items. In addition, the alert system 120may indicate a level of turbulence (e.g., by measuring the accelerationof the unmanned aerial vehicle 102) experienced during flight, which mayfurther indicate a level of risk to the delivery item(s) when thedelivery item is perishable.

In an embodiment, the alert system 120 may indicate a power level of thepower supply 110, which may be provided to and/or sensed by a secondarytransmitter/receiver device 130, such as a secondary drone 134 and/orbase station 136. For example, the alert system 120 may provide a powerlevel of the power supply 110 when the power level depletes beyond athreshold level. The alert system 120 may indicate the power level ofthe power supply 110 by, for example, visually displaying a colorpattern along the periphery of the unmanned aerial vehicle 102, such asperipheral lights that may gradually change from green to red as thepower supply 110 depletes. When the peripheral lights are all red, thealert system 120 may indicate that the power supply 110 is completelydepleted of power. In other embodiments, the alert system 120 mayindicate the power level of the power supply 110 by, for example,transmitting a power supply level to a secondary transmitter/receiverdevice 130 within a vicinity of the unmanned aerial vehicle 102.

The secondary drone 134 and/or base station 136 limy be configured toprovide power recharging and/or replacement power supply services to theunmanned aerial vehicle 102. For example, the secondary drone 134 may beconfigured to recharge the power supply 110 on the unmanned aerialvehicle 102 during flight and/or automatically replace the power supply110 by removing, using a replacement mechanism, the depleted powersupply 110 and inserting a charged power supply 110. The base station136 may include, but is not limited to, a shipment facility and/or abattery-charging station located at various locations, including ahomeowner's property. In some embodiments, the base station 136 may befully automated to replace and/or recharge the power supply 110. Inother embodiments, the base station 136 may utilize the assistance ofthe property owner where the base station 136 is located. For example,the property owner may initiate operation of the base station 136 tocause a replacement mechanism to remove the depleted power supply 110and insert another power supply 110.

The alert system 120 may provide the power level of the power supply 110to the transceiver 124, which may be transmitted, sensed, and/orreceived by the secondary transmitter/receiver device 130. In someembodiments, the alert system 120 may generate a request to thesecondary transmitter/receiver device 130 for recharging and/orreplacement battery services based on progress toward the deliverylocation, perishability of the delivery items, etc. The secondarytransmitter/receiver device 130 may indicate availability for theunmanned aerial vehicle 102 to recharge and/or replace the power supply110. In some embodiments, the unmanned aerial vehicle 102 may receive,from the secondary transmitter/receiver device 130, location informationof the secondary transmitter/receiver device 130, such as a relaylocation. In further embodiments, the secondary drone 134 may travelalong with the unmanned aerial vehicle 102 and provide power rechargingcapabilities to the unmanned aerial vehicle 102 during flight.

In some embodiments, the unmanned aerial vehicle 102 may be configuredto dispense a reward to the property owner and/or base station 136 whenrecharging and/or replacement of the power supply 110 is complete. Forexample, the unmanned aerial vehicle 102 may transmit, via transceiver124, a discount, rebate, coupon, reward points, payment, etc. forrecharging and/or replacing the power supply 110. In an alternativeembodiment, the unmanned aerial vehicle 102 may be configured todispense and/or release a reward item, such as a sample item, forrecharging and/or replacing the power supply 110. The reward item may beattached to the unmanned aerial vehicle via attachment device 17.6.

It should be understood that the alert system 120 can he programmableand/or customized based on the cognitive skills and/or abilities of theuser. For example, a recipient of the delivery item(s) who is colorblind may be able to program the alert system 120 with a differentpattern of lights rather than a non-color blind cohort. In anotherembodiment, if the combination of lights and/or audible signal from thespeaker affects the recipient's pets, the alert system 120 may beprogrammed and/or customized to better suit the recipient's environment.When the alert system 120 includes a color display, the color may beadjusted for individuals (e.g., recipients) having color blindness. Inaddition, sound effects generated from the alert system 120 and/orspeaker 122 may he employed for the vision impaired. In addition, themapping of color patterns may be controlled by the recipient (e.g., viauser device 132) and such mappings may be stored in a database, such asdatabase 510 of FIG. 5.

Now referring to FIG. 2, an exemplary system method 200 for aerialtransportation of delivery items using an unmanned aerial vehicle isillustratively depicted. The unmanned aerial vehicle (UAV) 202 mayinclude any of system 100 of FIG. 1. As illustratively depicted in FIG.2, the UAV 202 may be traveling to and from shipping location 201 anddelivery location 203 along delivery route 204. In some embodiments, theUAV 202 may be configured to communicate 206 with one or more secondarydrones 234A, 234B and/or one or more base stations 236A, 236B within thevicinity of the UAV 202. In some embodiments, the UAV 202 may transmit apower level to secondary drones 234A, 234B and/or base stations 236A,236B and/or request availability of recharging services. In furtherembodiments, the requests from UAV 202 may have different weightedvalues depending on, for example, perishability of the items attached tothe UAV 202, progress towards the delivery location 203 and/or shippinglocation 201, etc. For example, a request for recharging services may behigher from a UAV 202 carrying a perishable delivery item versus a UAV202 carrying a non-perishable item.

Now referring to FIG. 3, an exemplary system/method 300 for aerialtransportation of delivery items using an unmanned aerial vehicle isillustratively depicted. The unmanned aerial vehicle 302 may include anyof system 100 of FIG. 1. As shown in FIG. 3, the unmanned aerial vehicle302 may travel between a shipping location 301 to a delivery location303 during timeline t. As the unmanned aerial vehicle 302 progresses tothe delivery location 303, the alert system 320 is configured togenerate a status capable of being observed or otherwise perceived by anobserver 304 indicating information associated with the unmanned aerialvehicle 302. For example, the alert system 320 may illuminate a visualdisplay representing a progress level of the delivery. As shown in FIG.3, the alert system 320 on the unmanned aerial vehicle 302A at t₁indicates the start of the delivery of delivery item 305. At t₂, thealert system 320 on the unmanned aerial vehicle 302B indicates fiftypercent completion of the delivery. At t₃, the alert system 320 on theunmanned aerial vehicle 302C indicates one-hundred percent completion ofthe delivery, such as when the delivery item 305 is unfastened and/ordelivered at delivery location 303. Accordingly, the observer 304 isable to readily determine information associated with the unmannedaerial vehicle 302.

In an embodiment, the flight controller 502 may be configured to controlmovement of the unmanned aerial vehicle 102 by controlling therotational speed(s) and/or rotational direction(s) of each of themovement mechanisms 106 independently and/or collectively. For example,the flight controller 502 may be configured to rotate each of themovement mechanisms 106 in a single direction, or alternatively, theflight controller 502 may be configured to rotate each of the movementmechanisms 106 in opposing directions. In one embodiment, the flightcontroller 502 may be configured to control movement of the unmannedaerial vehicle 102 to avoid collision between the unmanned aerialvehicle 102, and various obstacles (e.g., trees, mountains, etc.).

In a further embodiment, the system 500 may include a navigation unit504, such as a global positioning system (GPS). The navigation unit 504may provide location information for particular shipping locations,delivery locations, and/or locations of one or more secondary devices130, such as a user device 132, a secondary drone 134 and/or basestation 136. Accordingly, the navigation unit 504 may provide theunmanned aerial vehicle 102 with navigation coordinates of variouslocations, including relay locations where the secondary drone 134and/or base station 136 can meet for power supply recharging and/orreplacement. The navigation unit 504 may include map coordinates of aparticular area and may provide such information to the flightcontroller 502, such that the flight controller 502 may direct theunmanned aerial vehicle 102 to a particular location.

In an embodiment, the system 500 may include a monitoring device 506.The monitoring device 506 may include a camera, a sensor, a radarsystem, or similarly functioning devices. In some embodiments, themonitoring device 506 may be configured to perform one or moreoperations as described above in relation to the camera 110, sensor 114,temperature controller 116, and/or stability controller 118 of FIG. 1.For example, the monitoring device 506 may capture one or more stillimages or video images and, using database 510, may perform imagecomparison with database images to determine whether or not the locationis safe to land and/or release a delivery item. In another embodiment,the monitoring device 506 may determine appropriate weight distributionof the delivery items along the unmanned aerial vehicle 102.

The system may include an alert system 508. The alert system 508 mayperform the operations as described above with reference to the alertsystem 120. In some embodiments, the alert system 508 may include areadily detectable indicator configured to generate a status and/or analert associated with the unmanned aerial vehicle 102, such as level oftask completion, an amount of time spent traveling, a dollar valueassociated with the delivery items, percentage of an order fulfillment,and/or a level of environmental variables traversed, such as a level ofturbulence or acceleration experienced by the unmanned aerial vehicle102 during flight. The alert system 508 may include a light display, anilluminated color display, a digital timer display, a clock display,and/or an electronic signal.

In an embodiment, the system 500 may include a database 510.

In a furtherembodiment, visual patterns and/or audible signals for the alert system508 may be stored in database 510.

The authentication unit 512 may be configured to verify recipientinformation and/or delivery location for delivery of the itemtransported by the unmanned aerial vehicle 102. In some embodiments, theauthentication unit 512 may include a scanner, such as a biometricscanner (e.g., thumbprint reader, retinal scanner, etc.) and/orRadio-frequency identification (RFID) scanner, to verify a recipient inorder to release the delivery item. In other embodiments, theauthentication unit 512 may include a scanner configured to scan abarcode, such as a quick response code, provided by the recipient. Forexample, the recipient may provide a barcode on a user device, such as acellular telephone and/or tablet, which the authentication unit 512 mayscan to verify identification of the recipient. In further embodiments,the authentication unit 512 may include a user interface configured toreceive a password input by the recipient. The authentication unit 512may compare the input password with a stored password, such as apassword stored in database 510, to verify the recipient. If theauthentication unit 512 fails to correctly verify the recipientinformation, the authentication unit 512 may transmit a command to theflight controller 502 and/or navigation unit 504 to return to theshipment location. In some embodiments, the alert system 120 mayindicate whether or not authentication has failed by, for example,visually displaying and/or announcing (e.g., via speaker 122) thatauthentication has failed.

In some embodiments, the system 500 may include a locking device 514.The locking device 514 may include, for example, electronic deadboltsand/or latches, a digital lock, an electronic lock, an electromagneticlock, and/or similar functioning devices. The locking device 514 may beconfigured to “lock” the unmanned aerial vehicle 102. For example, thelocking device 514 may lock the delivery item to the attachment device126 until authentication of the recipient is verified by theauthentication unit 512. Accordingly, the unmanned aerial vehicle 102may be in a “locked mode” until the appropriate recipient supplies theappropriate unlock input (e.g., password, verification, validation,etc.) so as to prevent thievery of such delivery items and/or deliveryto incorrect recipients. In some embodiments, the alert system 508 mayindicate that the unmanned aerial vehicle 102 is in a locked mode by,for example, illuminating one or more visual displays, generating anaudible alarm, and/or providing an electronic signal indicating that theunmanned aerial vehicle 102 is locked.

The risk analysis device 516 may be configured to evaluate a level ofrisk associated with one or more of the delivery items. In someembodiments, the risk analysis device 516 may determine a level of riskto delivery items that include perishable items. The risk analysisdevice 516 may determine whether or not a delivery item requiresimmediate attention upon delivery based on, for example, one or moreenvironmental variables (e.g., an amount of travel time, temperaturestraversed, and/or turbulence) experienced by the unmanned aerial vehicle102 during delivery. The risk analysis device 516 may be configured toprovide the level of risk associated with the delivery item to the alertsystem 508 to, for example, indicate that the delivery item requiresattention.

The system 500 may include a value adjustment device 518. The valueadjustment device 518 may be configured to adjust the value of thedelivery items depending on the risk level determined by, for example,the risk analysis device 516. For example, if the risk level to aperishable delivery item is high, the dollar value of the delivery itemmay be adjusted such that the value increases and/or decreases. As anexample, if the delivery item is ice cream and the temperature sensor114 determines that, during the delivery, the traversed temperatureexceeds a threshold value, then a dollar value and/or price charged forthe ice cream may be reduced since the ice cream may be partiallymelted. Alternatively, the value adjustment device may increase thedollar value associated with the delivery item if a delivery is madeearly and/or arrives hot, such as a pizza being delivered to a home.

In the embodiment shown in FIG. 5, the elements thereof may heinterconnected by a bus 501. However, in other embodiments, other typesof connections can also be used. Moreover, in an embodiment, at leastone of the elements of system 500 is processor-based. Further, while oneor snore elements may he shown as separate elements, in otherembodiments these elements can be combined as one element. These andother variations of the elements of system 500 are readily determined byone of ordinary skill in the art, given the teachings of the presentprinciples provided herein.

Now referring to FIG. 6, with continued reference to FIGS. 1-5, FIG. 6shows an exemplary method 600 for aerial transportation of deliveryitems using an unmanned aerial vehicle 102.

In block 602, the method 600 may include fastening one or more deliveryitems to an unmanned aerial vehicle 102 using an attachment device, suchas attachment device 126 of FIG. 1. In an embodiment, the delivery itemsmay be attached by determining appropriate placement of the deliveryitems to maintain a balanced load. The method 600 may include aeriallytransporting the deliver items along a delivery route, as illustrated inblock 604.

In block 606 the method 600 may further include generating a statusassociated with the unmanned aerial vehicle 102. The status may includea progress level and: or level of task completion, such as deliverystatus of an item to a predetermined destination, an amount of timespent traveling, a dollar value associated with the one or more itemsbeing transported, percentage of an order fulfillment, directionalmovement and/or environmental factors detected during flight. The statusmay he provided by one or more visual displays, acoustic signals, orelectronic signals, such as a light display, a speaker and/ortransceiver. The status is capable of being observed from multipleviewpoints and/or otherwise perceived by one or more individuals.

In some embodiments, generating a status associated with the unmannedaerial vehicle 102 may include detecting one or more environmentalfactors, such as temperatures, turbulence, tilt and/or accelerationtraversed along the delivery route, and displaying the one or moreenvironmental factors as the status, as illustrated in block 608. In afurther embodiment, generating a status may include evaluating a risklevel to the one or more delivery items and displaying the risk level asthe status, as shown in block 610. For example, the risk level may beevaluated when the traversed temperatures, the amount of traversedturbulence, or the tilt orientation exceeds a predetermined threshold.

In some embodiments, the status may he a value associated with the oneor more delivery items. In block 612, generating the status may includeadjusting the value associated with the delivery items based on the risklevel and/or indicating that the one or more delivery items requiresimmediate attention based on the evaluated risk level.

In block, 614, generating the status may further include indicating thepower supply level of the unmanned aerial vehicle 102 when the powersupply level depletes beyond a predetermined threshold, and receivinglocation coordinates of a secondary device configured to provide powersupply recharging and/or replacement. The secondary device may include auser device, a secondary drone, or base station.

In block 616, generating the status may further include authenticatingrecipient information upon delivery. When the recipient information isauthenticated, the delivery items may be released. In some embodiments,the status may indicate whether or not the recipient information isauthenticated or not. When recipient information fails to beauthenticated, the status may indicate that authentication has failedand/or the delivery item may remain fastened to the unmanned aerialvehicle.

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g. networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based email). Theconsumer does not manage or control the underlying cloud infrastructureincluding network, servers, operating systems, storage, or evenindividual application capabilities, with the possible exception oflimited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting for loadbalancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.

Referring now to FIG. 7, a schematic of an example of a cloud computingnode 710 is shown. Cloud computing node 710 is only one example of asuitable cloud computing node and is not intended to suggest anylimitation as to the scope of use or functionality of embodiments of theinvention described herein.
